Miggo AIRoot Cause Analysis

The vulnerability stems from using site-wide admin checks (reqAdmin) instead of repository-specific admin checks (reqRepoAdmin) for sensitive repository operations. The commit c3af3ff shows replacements of reqAdmin() with reqRepoAdmin() in three critical route groups: 1) /hooks endpoints, 2) /collaborators endpoints, and 3) /keys (deploy keys) endpoints. These routes required repository admin permissions but were previously guarded by global admin checks, allowing unauthorized access to repository management functions through the API.
